java - What is causing this animation flicker and how do I remove it? -

-

i have made tiny android application attempt resolve issue i've been seeing on different app. i'm trying achieve effect textviewstarts off screen, scrolls on.

what did looks it's working on 4.0.4, when use android virtual device (4.1.2) there "flicker" showing textview in original place before animation starts. i've noticed same thing on friend's tablet (4.4).

i uploaded video show issue here.

my layout:

<relativelayout     android:layout_width="match_parent"     android:layout_height="match_parent">     <textview         android:id="@+id/txtv"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/hello_world" />

during mainactivity's onresume() function move textview off screen starting position:

@override protected void onresume(){ super.onresume(); view v = findviewbyid(r.id.txtv); animation hidewords = animationutils.loadanimation(getbasecontext(), r.anim.hidetext); hidewords.setanimationlistener(new animationlistener() {     @override     public void onanimationend(animation animation) {         view v = findviewbyid(r.id.txtv);         int xoffset = (int)(v.getwidth() * .1);         relativelayout.layoutparams rlparams =              (relativelayout.layoutparams)v.getlayoutparams();         rlparams.setmargins(-1*xoffset, 0, xoffset, 0);         v.setlayoutparams(rlparams);     }

and there's button has onclick set function animateit() source of is:

public void animateit(view v){     v = findviewbyid(r.id.txtv);     animationset = new animationset(true);     animation showwords = animationutils.loadanimation(         getbasecontext(), r.anim.texnation);     as.addanimation(showwords);     v.startanimation(as); }

the animation slides view onscreen:

<set xmlns:android="http://schemas.android.com/apk/res/android"         android:shareinterpolator="false"         android:duration="700"         android:fillafter="true"         android:interpolator="@android:anim/linear_interpolator" >     <translate         android:fromxdelta="-100%"             android:toxdelta="0%"    /> </set>

so i'm trying figure out i've done incorrectly here that's causing flicker. right after button pushed first time text flickers on screen disappears , slides on expected.

any ideas?

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
